ABSTRACT: The results of experimental studies in the direction of the laser forming of nanostructured arrays of metal oxide crystals are presented in this paper. Laser synthesis of crystals of titanium oxide and aluminum oxide was investigated. Carbon nanotubes have been used to control the process of crystal growth. Formation of structures was carried out under the action of CW ytterbium fiber laser with intensity on the order 105 W/cm2. Laser irradiation of the initial target occurred with applying an external accelerating electric field. Various forms of metal oxide crystals were obtained. Whiskers with cross dimensions on the order of 100 nm have been found among the formed structures.
